Police set up a dragnet over seven blocks on Detroit’s east side Tuesday night after suspects in a traffic stop fled and one aimed a gun at an officer, a deputy chief said.

Police warned neighbors to stay indoors and call 911 if they “hear or see anything unusual.”

“We have huge response here on the scene,” said Deputy Chief Elvin Barren late Tuesday at a news conference at the scene. Police were looking for two suspects, ages 16 or 17. A third suspect who had remained at the vehicle was taken into custody, Barren said.

Officers from the gang intelligence unit were conducting a traffic investigation of a stolen Jeep Commander with three males inside at about 9:20 p.m. on the 19000 block of Hoover on Detroit’s east side when the driver, who had a handgun, and a passenger fled in separate directions.

As one officer gave chase, one of the suspects climbed a fence. As the officer in pursuit prepared to scale the fence, the suspect “turned on him with a handgun and the officer, fearing for his life, fired two to three rounds at the suspect,” said Barren.

“It’s unknown if any shots took effect,” he said. Police notified local hospitals to be on the lookout for anyone seeking medical attention for a gunshot injury, Barren said.

The incident initially was reported as shots fired at officers.

The officer at the fence injured his foot, Barren said. The weapon was recovered at the scene.

Police described one suspect as an African-American male with a white T-shirt and black pants. There was no description of the second suspect.

Barren called it a “high probability” that the suspects remained in the seven-block area that police cordoned off, but “they could have squeezed through before the actual perimeter was staged,” he said.

“We do have an active scene. We do have a perimeter set,” Barren said. “The weapon is in our custody. The vehicle is a stolen vehicle. It’s been confirmed.”

One woman following the news on DPD’s Facebook page wanted the suspects in custody. “We can’t sleep or nothing! Kid’s afraid,” she wrote.
